T4010 is a broad-band high performance “Bias-Tee”. It is design to supply DC power to a remote device such as a head-end pre-amplifier via the coaxial cable

This Bias-Tee (also known as a DC Inserter) features micro-strip line construction with select components to enhance the broad-band performance in the VHF/UHF frequency range.

This unit may be used with any remote device that was designed to receive DC operating power via a coaxial cable. It is housed in a cast aluminum case for ruggedness and high reliability.

BNC connectors are standard, with N and TNC connectors optional.

DC power (Positive or Negative polarity) is applied to the DC jack via a standard 5.5mm/2.1mm plug, a  6 foot power cord is supplied. For hard wired dc connection an EMI/RFI ceramic feed-thru with ground lug is available.
